What are the surface treatments of gabion net

Plastic covered gabion net is a net box made of hexagonal net (hexagonal net) woven by one-way twisting-and twisting metal wires for two weeks by machine. It is also called gabion-and pad with a thickness of 0.15-0.5m (including 0.5m). Gabion net pad is divided into several cells by diaphragm. In-order to strengthen the structural strength of gabion net pad, steel wires with larger diameter are selected at the edges-and ends of all panels.

Gabion mesh pad is divided into two categories: Plastic gabion mesh metal coating-and PVC / PE coating. The metal wire diameter used is different according to the size of the hexagon. The production process is to make Gabions-and pads after weaving, cutting, locking-and binding. Gabions-and pads are supplied in folded condition.

Basic parameters:

(1) Aperture: 60 * 80mm, 80 * 100mm, 80 * 120mm, 100 * 120mm, 120 * 150mm

The length of some double stranded wires shall not be less than 50mm to ensure that the metal coating-and PVC coating of some stranded wires are not damaged.

(2) Wire diameter: there are three wire diameters for gabion mesh - mesh wire, edge wire-and binding wire

1. The size of mesh is 2mm-4mm

2. The edge wire is usually larger than the mesh wire, with a thickness of 0.5mm-1mm

3. The binding wire is usually smaller than the mesh wire, most of which are 2.2mm

(3) Steel wire tension: not less than that of plastic coated gabion mesh

(4) Surface treatment 1. Electro galvanizing. The maximum zinc content is 10g / m2. Poor corrosion resistance

2. Hot dip galvanizing. The maximum amount of zinc can reach 300g / m2. Strong corrosion resistance

3. Golfan (zinc aluminum alloy). This is divided into two raw materials, Zinc-5% aluminum mixed rare earth alloy steel wire-and zinc-10% aluminum mixed rare earth alloy steel wire. Super corrosion resistance

4. PVC plastic coating. The thickness of plastic wrapping is usually 1.0mm, for example, 2.7mm,-and 3.7mm after wrapping. Strong corrosion resistance

(5) Interval: add an interval per meter in the long direction of the gabion net

(6) Scale: customizable

(7) Size of plastic covered gabion net compared with pore diameter-and wire diameter
